I have a question and think I know the answer, but I want to hear different opiniions.
I bought some Hornady 140 Gr FTX rubber tipped bullets for my 357 Mag rifle. Someone told me that I could use loading data for other 140 grain style bullets. So I tried 15.0 gr IMR 4227 and it seemed to seat ok on the cannelure. Then 16.0 grs, and there was a slight crimp just below the red rubber tip, where the bullet met the dies seater, and I tried 17.0 grs and got a heavy crimp there, because it was really compressed, and it did not crimp on the cannelure ie too much powder in the case. The manual for the "other" 140 gr bullet lists 17.8 grs as max. So it's not a maximum load for the bullet weight, but I don't think a normal style bullet would give a compressed load.
Would these be safe loads to shoot with a crimp just below the bullets expansion cuts which are just below the rubber tip?
